How rock paper is made and how do we get back paper pulp from waste rock paper for recycling?

Question

i want to know what are the additives added to paper pulp to obtain rock paper and how these additives are removed.

Answer 1

The main additive, that I know of, is a non-toxic resin, which is the primary binding agent.  In recycling, the non-toxic resin will have to be extracted, which may take a solvent.  this, in its own way, can present an ecological hazard (not the resin, but the extraction process).  However, if the re-pulping of the mineral-rich medium is done correctly, it may not be necessary to remove the resin, as it may provide added adhesive and "fiber" strength to successive generations of rock paper.  A great discussion from the Rock Paper page below.

Best of success, and thanks for introducing this fascinating topic!  I appreciate it very much.
